When I read articles like this, I am wondering if it supposed to be a farce for humor purposes or are they really serious. However, it reads like there are being serious.
There are a few things that do not make any sense, such as the following in item 4: A dedicated feed from your fusebox, just for your hi-fi and not shared with any other items, is a good thing to do regardless. And yes, you probably need a pretty serious system to really hear this but rest assured, there is some science behind this rumour. In the US, most homes are supplied by two hot wires that have 120 volts potential to ground and 240 volts between each hot feed. Therefore, each hot wire will supply multiple circuits in your home. If there is a device creating line noise on a circuit, it will impact other circuits that share the same hot feed from the transformer. Therefore, in terms of line noise, having a dedicated circuit to supply your hifi set up will probably not help, unless the hifi system draws a lot of current requiring its own circuit. This is a UK article, and I am not sure about the wiring for UK systems, but my guess the conclusions are similar. This issue ignores that in a very expensive system, the designer will put a lot of filtering the input power to strip out line noise. Even cheaper car audio systems do this to strip out alternator noise which is very audible to the lower frequencies. Item 5, besides the phrase "squash balls" made me laugh The subsidiary point is that while CD players (for instance) don't show up the effects of vibrations as obviously as, say, turntables, simple things like heavy footfall, cars whizzing by your home, planes overhead or even the sound from your speakers especially at loud volumes can make data-reading mechanisms work harder, which can affect the sound you get from your system. If a noise from a car or plane can be heard in the room, then who cares if it might actually impact the ability of the CD player to read music. It also ignores that CD players have buffering and multi samples to reliability read the data. ------------------------------------------------------------------------ P Nelson's Profile: http://forums.slimdevices.com/member.php?userid=58158 View this thread: http://forums.slimdevices.com/showthread.php?t=117268
